A couple of things I see in:

Issue #177

Each discussion goes through a two stage payout. The first one is nearly identical to what currently happens on a new discussion except that we are weighting payout times by 12 hours instead of 24.

So are payments now every 12 hours?

There is a second voting period set to 30 days after the first payout. This should help posts that don't have immediate viral success accumulate votes and have more consistent payouts in the long run.

Awesome!!

After the second payout a discussion becomes "frozen". The discussion is no longer editable and new replies are disabled. Users can still vote on comments in these discussions as a "nod" to the author without costing their posting power or awarding reward shares.

This is super cool! its going to be huge for stats and morality LOL.
